The purpose of this study is to examine whether an exergaming, aerobic physical education (PE) curriculum is acceptable and elicits improvements in behavioral self-regulation and classroom functioning among children with behavioral health challenges attending a therapeutic day school. After following an approved consent/assent process, children attending the school were randomized by classroom to take part in either 7 weeks of the experimental PE curriculum, or 7 weeks of the standard PE curriculum; after a 10 week washout period, children then crossed over into the other arm.
